Hi,
For Some Reason, the mailing list strips all *.java attatchments.
I think you'll have to send your files direct to armin.

Hi Wara,
Torque relies on generated persistent Java classes that contain special
code to interact with the rest of the framework.
OJB provides persistence for POJOs (Plain old java objects).
OJB does also cover more details like polymorphism, inheritance, lazy
loading etc.
YOu may well use Tor

Hi Bonnie,
Your code looks correct. But I'm in doubt about retrieveAccountByNumber().
What happens in this method?
What's really strange with the generated SQL that OJB tries to check
if there is an existing account with ID=5
But the insert is done with the value ID=1 !

Hi, all,
My project has potentially huge result sets, so there is a question to use
OJB.
Suppose a query returns thousands of objects, but the results are always

scenario?

is a subclass of C and C does not have the timestamp field) and a D

To solve this problem:
Be sure you are generating java 1.3 class files.

Hi.
I'm new to OJB and OR mapping technology. I look at
torque document and notice that it's similar to OJB
persistence broker api.
So, please tell me what is the different between these
frameworks?
Best Regards.

Using your logic, I'm trying another (less efficient I know) method of

Ron,
Thanks for the prompt response... your code looks great... except for a
few items. criteria.addGroupBy() and addOrderBy*() have been
deprecated... I think the same methods on the query object are preferred
now. That's sort of irrelevant though.

This should create the query you need.
